Open Secret

Wei Wu Wei is the pseudonym of a person who wrote a series of invaluable books from 1958 to 1974, explaining all the intricacies of non-dual teachings - not only Advaita but also Buddhism (Chan and Zen) and Daoism. Deeply philosophical and poetic, these books leave a lasting impression on everyone who picks them up.
One of Wei Wu Wei's most beloved books, "Open Secret," reveals to us the true nature of the "self," as well as time, space, and enlightenment itself. This work includes an extensive commentary on the "Heart Sutra," regarded by Buddhists as the quintessence of the Buddha's wisdom.
